The projector LS740W by Viewsonic utilizes DLP technology and, according to the spec sheet, achieves 5000 ANSI lumens, a contrast of 300000:1 at a resolution of WXGA 1280 x 800. The manufacturer lists the lifespan for this model at 20000 hours – calculating to 13.7 years at four hours of use per day. For basic image adjustment, the device is equipped with horizontal and vertical keystone correction, allowing digital compensation for trapezoidal distortion at angled projection setups. A look at the light output reveals: The 5000 ANSI lumens are sufficient to illuminate an image width of up to 718 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 479 cm. For media input, video signals up to 1080P and 4K are supported. Furthermore, the model supports 360° projections for highly flexible deployment scenarios.
